My book says that the tendency to have zero field outside and a uniform field inside become more and more effective as the solenoid is more and more tightly wound.Can someone justify this statement.
I was facing problem for a point outside the solenoid as when I was calculating,magnetic fields in one direction became strong when coil is tightly wound from a stretched one.

$\begingroup$PLease tell us what book this is, and if possible post a link or a scan of the pertinent page. Also, how is the solenoid wound: continuous helix, or counter-windings like in humbucker coils?$\endgroup$
